I'm not sure how close in to the city you are, but Goldberg's Bagels has casseroles and soups in their freezer case by the door. They're decent, and my in-law's get them when company stays more than 1 night to feed the group. Anyway, the closest one to this area is on West Paces Ferry right off of I-75.In Ivy Walk in Smyrna/Vinings Dinner A'Fare has opened. I haven't tried it, but it's one of those places where you can prep and freeze meals - not casseroles. This might be a good choice for you to stock up several dinners.
